Every table is different. Every opponent is different. It is HARD to get paid BIG on big hands... because you NEED your opponent to have something they can bet or call with.
When you flop the full-house ask yourself "what hands can I my opponent have that he will call with" if you can't think of any, then perhaps it is better to check to give your opponent a chance to bluff.
Agreed. This is tricky for a few reasons...as mentioned we hold pretty much everything and the second reason is because it takes a little hand-reading to predict if they have anything. Sad truth is that you won't get paid if they got nothing and won't bluff. If they do have a hand, then it becomes a guessing game or sorts to figure out how much value you can get from this hand.
Probably checking the flop makes sense, unless you think they won't believe a flop bet (maybe you've been c-betting a ton). The question is if we should be on the Turn, River, or not at all. I'd bet whenever you think they might call with a worse hand. Something like an Ace or King hitting the board (but not a card we had for Full House) might be a "scare card" but might also connect with the opponent(s), so a decent bet when that card hits might induce them to play back at you if they paired said card.
Ironically, this spot is tough to get value from, despite being such a monster hand. Same with Four of a Kind, Royal Flushes or anything really unlikely.
Play it carefully. If there are a lot of players the chance is big that someone else also has a FH. Even better one.
It is good to always consider if the opponent has a better hand. However, we can't be scared of Full House over Full House too much. It is rare enough for one in a hand; two or more is super unlikely so there isn't enough reason to suspect the opponent(s) have us beat now. If they do, then it is a cooler and part of the game.
I've correctly folded Full House over Full House several times before, but this is highly dependent on hand reading and
tells. From a purely math approach, or no tells, then we should be willing to assume our Full House is best by far most of the time. I certainly wouldn't call the probability of a better Full House facing us a "big" chance
